High Refractoriness Chrome Magnesite Refractory Brick for Cement and Lime Kiln Furnace
High Refractoriness Chrome Magnesite Refractory Brick for Cement and Lime Kiln Furnace
What is the details of our chrome magnesite refractory bricks?
Magnesium chrome brick to magnesium oxide (MgO) and chromium oxide (Cr2O3) as the main ingredient,periclase and spinel as main mineral components of refractory products.
1.Common Magnesium chrome brick is made by sintered magnesia and refractory level chrome ore as raw materials. The space between refractory grains is bonded with silicate.
2.Direct-bonded Magnesium chrome brick is made by chrome ore with low content of impurities and pure magnesite,firing at the temperature above 1700°C.
3.Semi-rebonded and Fuse-rebonded magnesium chrome brick are made by fused magnesite chrome sinter.
